NMR and Conductivity Study of Polymer Electrolytes in the Imide Family: P(EO)/Li[N(SO2CnF2n+1)(SO2CmF2m+1)]

Abstract

Size does not matter, at least for the diffusion of anions in poly(ethylene oxide). The conductivity and diffusion data obtained as a function of temperature for a series of perfluoroalkyl sulfonimides (see picture) indicate complete dissociation and obey the Nernst–Einstein equation rather than Stokes' law.
